Hi Robert,
Well in fact I use jack with POSIX shm for a few month now and every 
thing is fine. I can run all jack audio app I have without any problem 
with my cheap SBLive. I have no xrun with -p1024 and a few when 
switching desktop or starting apps with -p512 (which seems to be the 
normal behaviour with a SBLive).
But it seems that there is a preference for SysV shm (this is the 
default in configure !!) so I was wondering why.
